I’ve always had a bit of a thing for hats, especially wide brim hats. And now, with a growing pattern collection of my own, I just had to have a go at designing my own — which brings me to the Blossomia Sun Hat!
As much as I love hats for the style, they’re also brilliantly practical — especially if you’re a bit of a garden potterer like me. I burn quite easily, and my sister (who’s an aesthetic doctor and very clued-up on skincare) is always reminding me how important it is to protect your skin from sun damage. So this hat isn’t just a pretty accessory — it’s a skin-saving essential.
About the Pattern
The Blossomia Sun Hat is a confident beginner pattern, particularly if you’ve had a go at patchwork or curved seams before. It’s made up of a crown, side pieces, and a lovely wide brim — perfect for keeping your face shaded while you’re out in the garden, on a walk, or enjoying a cuppa in the sunshine.
I made the sample you can see in the photos and video using:
A medium-weight upholstery linen for the outer
A striped medium-weight upholstery cotton for the lining
Both were gorgeous remnant finds from the lovely Elizabeth Stanhope Interiors in Oakham, Rutland — highly recommend popping in if you’re nearby!
To give it structure, I used:
Medium fusible interfacing for the brim pieces – like this one.
Lightweight fusible interfacing for the crown – such as this one.
And my own homemade starch spray (the recipe’s in the instructions!) to stop the brim from being too floppy.
The trickier part...
…Sewing the Crown Top. If there’s one part that might make you pause for a moment, it’s attaching the round crown top to the side crown pieces. But don’t worry — it’s do-able with a few handy tips:
Tips for Sewing a Round Top Crown:
1. Don’t worry about the raw edges
When you join the side crown pieces, the top edge might look a bit smaller than the circular top. That’s completely normal! The key is to match where the seam will be sewn, not the edges of the fabric. I find pins work better than clips here — clips tend to force things into lining up where you don’t really want them to.
2. Give yourself a bit of leeway
Even the tiniest difference in seam allowance can change how the pieces fit. Rather than trying to make everything line up edge-to-edge, gently ease the circle in as you go — let the fabric adjust naturally.
3. Pin in quarters
Fold both the crown top and the upper edge of the side crown into quarters (fold in half, then in half again) and mark with pins. This helps you distribute the fabric evenly. Match up the quarter points, then fill in with more pins between them.
4. Hand-baste if you need extra control
Not everyone loves a bit of hand sewing, but basting is a great trick here. A few loose stitches to hold the pieces together before machine sewing can make all the difference — it helps prevent puckering and makes it easier to control the fabric.
5. A good press goes a long way
Once your top crown piece is attached, give the seams a good press with the iron. It really helps smooth everything out and gives your hat a polished, professional finish.
Optional Extras
Although the pattern includes instructions to starch your hat (and I highly recommend you do), you may wish to have a firmer brim. In this instance, i recommend:
Sew millinery wire into the edges of the brim to allow for shaping. I recommend this wire.
Or add a layer of stiff interfacing such as Decovil Light or Vlieseline , cut to the same shape as the brim, and insert it after Step 22 in the instructions (once the brim pieces are assembled).
